# Self-induced topological transitions and edge states supported by nonlinear staggered potentials

@article{Hadad2016SelfinducedTT, title={Self-induced topological transitions and edge states supported by nonlinear staggered potentials}, author={Yakir Hadad and Alexander B. Khanikaev and Andrea Al{\'u}}, journal={Physical Review B}, year={2016}, volume={93}, pages={155112} }

The canonical Su-Schrieffer-Heeger (SSH) array is one of the basic geometries that have spurred significant interest in topological band-gap modes. Here, we show that the judicious inclusion of third-order Kerr nonlinearities in SSH arrays opens rich physics in topological insulators, including the possibility of supporting self-induced topological transitions, as a function of the applied intensity. We highlight the emergence of a class of topological solutions in nonlinear SSH arrays…
